Instrumentation

This gem adds simple sugar for ActiveSupport::Notifications

Subscribe to notifications

require 'instrumentation'

class UserNotifier
  include Instrumentation

  subscribe_to 'user.update'

  def self.call(*event)
    say "Processing..."
  end
end

If you use Instrumentation by ActiveRecord model you can instrument model's changes and create one subscriber to all produced events

require 'instrumentation'

class User < ActiveRecord::Base
  include Instrumentation

  instrument_to 'models.mutations'
end

class ModelsMutationsSubscriber
  include Instrumentation

  subscribe_to(/models.*/)

  def self.call(channel, _, _, _, payload)
  end
end

Installation

Add this line to your application's Gemfile:

gem 'instrumentation', github: 'fatum/instrumentation'

And then execute:

$ bundle

Or install it yourself as:

$ gem install instrumentation
